Leonard Shelby:
I have to believe in a world outside my own mind. I have to believe that my actions still have meaning, even if I can't remember them. I have to believe that when my eyes are closed, the world's still there. Do I believe the world's still there? Is it still out there?... Yeah. We all need mirrors to remind ourselves who we are. I'm no different.

Leonard Shelby:
I'm not a killer. I'm just someone who wanted to make things right. Can't I just let myself forget what you've told me? Can't I just let myself forget what you've made me do. You think I just want another puzzle to solve? Another John G. to look for? You're John G. So you can be my John G... Will I lie to myself to be happy? In your case Teddy... yes I will.

Leonard Shelby:
Memory can change the shape of a room; it can change the color of a car. And memories can be distorted. They're just an interpretation, they're not a record, and they're irrelevant if you have the facts.

Leonard Shelby:
I don't even know how long she's been gone. It's like I've woken up in bed and she's not here... because she's gone to the bathroom or something. But somehow, I know she's never gonna come back to bed. If I could just... reach over and touch... her side of the bed, I would know that it was cold, but I can't. I know I can't have her back... but I don't want to wake up in the morning, thinking she's still here. I lie here not knowing... how long I've been alone. So how... how can I heal? How am I supposed to heal if I can't... feel time?

Natalie:
But even if you get revenge you're not gonna remember it. You're not even going to know that it happened.

Leonard Shelby:
My wife deserves vengance. Doesn't make a difference whether I know about it. Just becuase there are things I don't remember doesn't make my actions meaningless. The world doesn't just disappear when you close your eyes, does it? Anyway, maybe I'll take a photograph to remind myself, get another freaky tattoo.

Natalie:
No, don't just recite the words. Close your eyes... and remember her.

Leonard Shelby:
You can just feel the details. The bits and pieces you never bothered to put into words. And you can feel these extreme moments... even if you don't want to. You put these together, and you get the feel of a person. Enough to know how much you miss them... and how much you hate the person who took them away.

Natalie:
Is that what your little note says? It must be hard living your life off a couple of scraps of paper. You mix your laundry list with your grocery list you'll end up eating your underwear for breakfast.

Leonard Shelby:
Sammy Jankis wrote himself endless notes. But he'd get mixed up. I've got a more graceful solution to the memory problem. I'm disciplined and organized. I use habit and routine to make my life possible. Sammy had no drive. No reason to make it work.

Leonard Shelby:
When I looked into his eyes I thought I saw recognition. Now I know. You fake it. If you think you're supposed to recognize somebody you, you just pretend. You bluff it to get a pat on the head from the doctors. You bluff it to seem less like a freak.

Leonard Shelby:

So where are you? You're in some motel room. You just - you just wake up and you're in - in a motel room. There's the key. It feels like maybe it's just the first time you've been there, but perhaps you've been there for a week, three months. It's - it's kind of hard to say. I don't - I don't know. It's just an anonymous room.

Leonard Shelby:
I meet Sammy through work. Insurance. I was an investigator. I'd investigate the claims to see which ones were phony. I had to see through people's bullshit. It was useful experience, 'cause now it's my life.
